Designed by Robert G. Henry Jr. and built by the German yard Dedood And Sohn Yacht Und Boatwerks starting in 1960, this distinctive 32-footer represents classic European yacht design from the early 1960s. With only 14 hulls ever constructed, the International 500 stands as a rare example of traditional long-keel cruising yacht architecture. The yacht's substantial 11,200-pound displacement and deep 4.75-foot draft create exceptional stability and seaworthiness, making her well-suited for serious offshore cruising. Her long keel configuration provides excellent directional stability and a forgiving helm, though at the expense of maneuverability in tight quarters. The masthead sloop rig with 496 square feet of sail area delivers respectable performance while remaining manageable for a small crew. Built using a combination of wood and fiberglass construction methods, these yachts reflect the transitional period when builders were experimenting with composite techniques. The impressive comfort ratio of 37.41 indicates a motion that favors comfort over speed, while the capsize screening formula of 1.55 suggests good stability characteristics for offshore work. This is a yacht designed for those who prioritize seaworthiness and traditional sailing qualities over racing performance or shallow-water versatility.
